[0022] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1 to 3 According to an embodiment of a display screen 100 of the present invention, the display screen 100 includes a plurality of module units 1 , a plurality of magnetic units 2 , an adjustment unit 3 and a support unit 4 .

[0024] Each module unit 1 includes a module body 11 and a plurality of fixing posts 12. The module units 1 are connected to each other, and in this embodiment, two adjacent module units 1 are used as an example for illustration, but the number and arrangement of the module units 1 can be adjusted according to the size of the display screen 100. In addition, in this embodiment, the fixing posts 12 are arranged at intervals and surround each module body 11, and the fixing posts 12 correspond to the magnetic units 2 respectively, but the number and arrangement of the fixing posts 12 and the magnetic units 2 are not limited to this. For ease of explanation, the following description is based on the module body 11 of the two module units 1 that is relatively lower in height, and is coordinated with one of the fixing posts 12 and one of the magnetic units 2 provided on the module body 11.

[0025] See Figure 3 and Figure 4 The module body 11 has an outer panel 111 and an inner panel 112 opposite to the outer panel 111. The fixing post 12 is connected to the inner panel 112 and extends from the inner panel 112 away from the module body 11. It has a column 121 and an internal thread 122. The column 121 is cylindrical and hollow, and has a fixing space 123 for fixing the magnetic unit 2. The internal thread 122 is formed on the inner ring side of the column 121.

[0026] The magnetic unit 2 is arranged in the fixed space 123 of the fixed column 12 and includes a magnetic base 21 and a first magnetic group 22. The magnetic base 21 is cylindrical and has a magnetic base body 211 and an external thread 212, and the length of the magnetic base body 211 is shorter than the length of the column 121. The magnetic base body 211 is formed with a mounting groove 213 with a notch facing the inner plate surface 112 and for mounting the first magnetic group 22, and has a supporting surface 214. The external thread 212 is formed on the outer ring side of the magnetic base body 211, and the external thread 212 can be screwed into the internal thread 122, so that the magnetic base 21 can be threadedly connected to the fixed column 12 and can move the magnetic base 21 up and down relative to the fixed column 12. The first magnetic group 22 is arranged in the mounting groove 213 and has a plurality of first magnetic members 221 arranged alternately with N poles and S poles.

[0027] The adjustment unit 3 can be detachably provided on the module body 11. More specifically, the adjustment unit 3 is provided on the outer panel 111 of the module body 11 whose height needs to be adjusted, and the relative position of the adjustment unit 3 on the outer panel 111 corresponds to the magnetic unit 2. The adjustment unit 3 includes an adjustment block 31 and a second magnetic group 32. The adjustment block 31 is formed with a receiving groove 311 for accommodating the second magnetic group 32, and the notch of the receiving groove 311 faces the outer panel 111. The second magnetic group 32 is provided in the receiving groove 311 and has a plurality of second magnetic members 321 arranged alternately with N poles and S poles. The second magnetic member 321 corresponds to the first magnetic member 221, and can drive the magnetic base 21 on which the first magnetic group 22 is installed to rotate relative to the fixed column 12 by rotating the adjustment block 31.

[0028] In this embodiment, the first magnetic group 22 and the second magnetic group 32 are each of four polarities. However, in other implementations, the first magnetic group 22 and the second magnetic group 32 can also be of two polarities or four or more polarities, and their number and arrangement are not limited thereto.

[0029] The support unit 4 includes a support body 41 and a plurality of iron pieces 42. The support body 41 is arranged on one side of the inner plate surface 112 and has a protrusion 411 arranged on the edge of the module body 11, and is formed with a plurality of through holes 412 arranged at intervals and corresponding to the magnetic unit 2 and the fixing column 12 respectively. The protrusion 411 has a support surface 413 that can contact the inner plate surface 112. Each iron piece 42 has a head 421 and a rod body 422. Each head 421 is magnetic and faces and corresponds to the first magnetic group 22, and has a contact surface 423 that can contact the abutment surface 214 of the magnetic base body 211. Each rod body 422 is connected to the corresponding head 421 and is respectively arranged in the corresponding through hole 412 so that the iron piece 42 is fixed to the support body 41.

[0030] The following describes the operation method of adjusting the height of the module unit 1.

[0031] See Figure 5 and Figure 6 , the module unit 1 has not yet adjusted its height (such as Figure 5 As shown), there is a gap between the iron piece 42 of the support unit 4 and the magnetic base 21 of the magnetic unit 2. Then, by continuously rotating the adjustment block 31, the second magnetic group 32 corresponding to the first magnetic group 22 drives the magnetic base 21 to move toward the iron piece 42, and the gap between the magnetic base 21 and the iron piece 42 is continuously reduced until the abutting surface 214 of the magnetic base body 211 abuts against the contact surface 423 of the iron piece 42 (as shown). Figure 6 Then, the adjusting block 31 is further rotated. Since the iron piece 42 is fixed to the supporting body 41 and the head 421 of the iron piece 42 cannot move relative to the supporting body 41, the magnetic base 21 rotates in place to move the column 121 away from the iron piece 42, thereby driving the module unit 1 to move away from the iron piece 42 and separating the protrusion 411 of the supporting body 41 from the inner plate 112. In this way, the height of the module unit 1 can be adjusted without disassembling the module unit 1, so that the height of the module unit 1 can be consistent with that of the adjacent module units 1.

[0032] In summary, the display screen 100 rotates the adjustment unit 3 disposed on the outer panel 111, driving the magnetic unit 2 disposed on the inner panel 112 to rotate and causing the magnetic base 21 to continuously move toward the iron piece 42, so that the gap between the magnetic base 21 and the iron piece 42 is gradually reduced until no gap exists. When the adjustment unit 3 is continuously rotated to apply a force to the iron piece 42, the reaction force generated by the iron piece 42 can push the module unit 1 to move in a direction away from the iron piece 42. In this way, the display screen 100 can adjust the height of the module unit 1 by simply rotating the adjustment unit 3 without disassembling the module unit 1. This is not only convenient to operate and time-saving, but also prevents damage to the lamp beads on the display screen 100, so the purpose of the present invention can be achieved.

[0033] However, the above is only an embodiment of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
